Ingredients

Scale

Potato Crust

  • 600 g (1.3 lbs / about 4 medium) potatoes, peeled and grated
  • 80 g (¾ cup) mozzarella cheese, grated
  • 2 large eggs
  • 2 tablespoons fresh parsley, chopped
  • Salt and pepper to taste (to season the crust)
  • 1 teaspoon dried oregano
  • 2 tablespoons olive oil

Filling

  • 150 g (5 oz) baby spinach
  • 200 g (7 oz) champignon mushrooms, sliced
  • 1 green onion, chopped
  • 1 garlic clove, minced
  • 2 tablespoons olive oil
  • Salt and pepper to taste (to season the filling)
  • 1 teaspoon dried oregano

Topping

  • 100 g (1 cup) mozzarella cheese, grated
  • 120 g (4 oz) mozzarella fior di latte, torn into pieces
  • 30 g (¼ cup) Parmesan cheese, grated
  • Fresh parsley for garnish

Instructions

  1. Preparation: Grate the potatoes and place them in a bowl with cold water and a pinch of salt. Let them soak for 15 minutes to remove excess starch, which will help achieve a crispier crust.
  2. Sauté Vegetables: While the potatoes soak, heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the chopped green onion and sauté until softened, about 2 minutes. Add the baby spinach, season with salt and pepper, and cook until wilted, approximately 2-3 minutes.
  3. Cook Mushrooms: Add the sliced mushrooms to the pan with the spinach. Season with salt, pepper, and dried oregano. Add the minced garlic and cook for about 8 minutes until the mushrooms are golden and all liquid has evaporated. Remove from heat and set aside to cool slightly.
  4. Prepare Potato Mixture: Drain the soaked potatoes thoroughly, squeezing out any excess water with your hands or a clean kitchen towel to ensure a dry mixture. Transfer potatoes to a mixing bowl and combine with 80 g of grated mozzarella, eggs, chopped parsley, salt, pepper, and dried oregano. Mix well to incorporate all ingredients.
  5. Preheat Oven and Prepare Pan: Preheat your oven to 200°C (390°F). Brush a 9-inch (23 cm) round baking dish or springform pan with olive oil to prevent sticking.
  6. Form Potato Crust: Press the potato mixture firmly into the prepared baking dish, spreading it evenly on the bottom and pressing up the sides to create a crust approximately 2 inches high. This will serve as the pie shell.
  7. Bake the Crust: Place the baking dish in the oven and bake the potato crust for 35-40 minutes until the edges are golden brown and crispy.
  8. Add Filling and Toppings: Remove the crust from the oven and carefully spoon the mushroom and spinach mixture into the center of the crust. Evenly sprinkle the remaining grated mozzarella, place torn pieces of mozzarella fior di latte on top, and finish with grated Parmesan cheese.
  9. Final Bake: Return the pie to the oven and bake for an additional 10-15 minutes, or until the cheeses have melted, become bubbly, and have golden spots.
  10. Cool and Serve: Let the potato pie cool for 5 minutes before serving. Garnish with additional grated Parmesan and freshly chopped parsley for a fresh herbal note.

Notes

  • Make sure to thoroughly squeeze out water from the grated potatoes to keep the crust crispy and prevent sogginess.
  • Use a clean kitchen towel or cheesecloth to remove as much moisture as possible from the potatoes.
  • If desired, substitute champignon mushrooms with cremini or button mushrooms depending on availability.
  • You can add a pinch of nutmeg to the spinach and mushroom filling for extra warmth and flavor.
  • Letting the pie cool slightly before slicing helps the filling set better and makes for easier serving.
  • This pie is vegetarian but not vegan due to the use of multiple cheeses and eggs.
